. OPERATING MEcHANIsM FOR WATERI-oL-OSET rLUsIIING-TANKS.

To all-whom it may concern: l

Beit known lthat I, CHARLES PFAU, a

citizen of the 'United States, residing at'Cincinnati, lin the county'ofHamilton -and State of Ohio, Vhave' invented certain new and usefulImprovements in Operating Mechanisms for WatereCloset Flushing-Tanks, of

which the'ollowin is a specication.

tachments, and the object is to provide a mechanism for operating theescape valve of thefiiushing'tank by a movement in either direction, so@hat ignorance of the design z.' of thej mechanism will not result indam- '-'a.'g je to' theparts -by exerting undue strain .upontliem'in anlei'o'rt tov operate them "r [the wrong direction.-

different makes, some of which are designed to be operated by moving thehandle upward and others of which are designed to berop'erated by movingthe handle downward. vThe result of such a condition is tha-tusers, notbeing able to conveniently determine the direction in which the handleis to be operated, will be as likely to attempt My invention re atesto'water closet at- .vidinga handle forthe operation of the mechanismand -so connecting it to the mechanism. that the raising of the handleor the depression of it will operate the mechanism in the same directionand thus operate it properly. As illustrated, my improvement 'is.embodied with a water closet flushing tank l, provided interiorly witha valve 2 coperating with a seat 3 in the escape pipe 1, this valvebeing adapted to be lifted from its seat by means of an arm 5 connectedat one end to the .valve and by means of the rod 6, and fulcrumed in abracket 7 on the upper edge of the tank at the rear, under the cover 8of the tank. A. rod 9 extends down from the other end .of the arm 5,this rod extending between the lining l0 lof the tank and its-rear wall11- and extending through theI bottom .12 of the tank.

. The handlev 13 for operating the escape valve 2 extends pastthe frontof the tank -and has a fulcrum 14C in a bracket 15 extending down fromthe lower sideof the bottom of the tank near thefront thereof.

This handle 13 extends rearwardly of its ltension'fof the bracket 15which extends' rear'- wardly.- `.The brackethas arms 19 flanking thelever 1"?l adjacent to the ulrum 18 to Guide the lever when it movesdownwardly.

lhe handle 13 has a rearward projection 2O on its-rear end, neanitsupperside, and, as

,the part of it forward o-f this fulcrum being raised and the partel tothe rear being depressed, pulling down on the rod 9 and act infr throughthe arm 5 and rod 6 to raise the valve 2 from its seat 3. If the forwardextension of the handle 13 is raised, it will turn onits fulerum4 14 andits rearward extension. will be depressed while, no vrelative Vmovementbetween the handle 13 and the lever 17 being permitted, the lever 17will .be carried` bodily downward, so that itsrear end this time alsowill be depressed, raising the valve 2 Vfrom its seat in the sameina-nner. Thus, whether the forward, ex-

tension of the handle 13', which is the only.

part readily observed by the user, is depressed-or raised, the valvewill be operated in exactly the same manner, and at no time .will therebe any undue strain'on the parts due toan attempt to operate them in thewrong direction.

'As illustratedin the drawings, the lever 17 is bifureated,1 having twomembers between which is 'received the rear end of the handle 13 beingconnected thereto by means of the pivot pin 16 extending through thehandle and the members 22, while the lug 21 isintegral with the leverand lille the space between its members 22 near the lower side ofthelever to the rear of the rear end of the handle, the handle 13 havingtherearward projection 20 to engage with this lug 21. However, it will beunderstood that my iniprovement is capable of considerable modification,as wellfas adapted to be adjusted in various positionsl for operatingupon mechanisms of different design without departing from the scope andspirit of the invention, and, therefore, I do not wish to be understoodas limiting myself to the precise description and illustration containedtherein,

` but What I claim as new and desire to secure by Letters'Patent is:

1. The combination of operating mechanism for water closet flushingtanks, with a fulcrum to which the handle isi-confined, a lever, and afulcrum for the lever with- `which it may engage and disengage, saidhandle, and one end of said lever being connected to form a,rule-.jointbetween said fulcrums, andtheot-he'r end of the lever beingconnected to the mechanism tov be operated,

whereby the movement of. the handle in itlienottwo directions will movethe operconnection with vthe handle, with which for the purposes hereinyset extending forwardly of the tank, a..,ful
